Benefits of technology

The patent aims to make military warheads less vulnerable to external impacts and reduce the likelihood of accidental ignition of the explosive charge. The invention aims to achieve this by creating distribution networks of initiation points for the explosive charge.

Problems solved by technology

The military devices that include such pyrotechnic charges and their ignition devices are constantly changing to become more effective while offering a high level of vulnerability to external attacks, for example to the explosions due to the explosion of other charges, bullets, etc.
The advantage of this pyrotechnic charge configuration with selection of the detonator lies in its effectiveness in destroying the target but has the drawback of high vulnerability to external attacks.

Embodiment Construction

[0058]FIG. 6 shows an oriented multiple-burst pyrotechnic charge according to the invention.

[0059]The pyrotechnic charge of FIG. 6 comprises an explosion generator 50 placed at the center of an explosive charge (or explosive) 52.

[0060]The surface of the explosive charge is divided into segments 51, S2, . . . Si, . . . Sn each comprising, and according to a main characteristic of the invention, interleaved partial ignition networks.

[0061]For example, in the case of the pyrotechnic charge of FIG. 6, each of the segments comprises two partial networks Ra1, Rb1, for the segment S1, Ra2, Rb2, for the segment S2, Rai, Rbi for the segment Si of number i and so on to the last segment Sn comprising the networks Ran and Rbn.

[0062]Each of the two interleaved partial networks of the pyrotechnic charge comprises a respective detonator sited remotely from the explosive surface for its activation, Dta1 for the network Ra1, Dtb1 for the other network Rb1 of the segment S1, Dta2 for the network Ra2,...

Abstract

Pyrotechnic charges that include an explosion generator and an explosive having an outer surface divided into n segments, each segment having kq multiple ignition points for the explosive, k and q being integer numbers greater than 1. The kq multiple ignition points for the explosive are linked by ignition lines forming, for each segment, at least two interleaved partial networks for synchronous ignition of the kq multiple ignition points, each of the partial synchronous ignition networks being linked to a respective partial network detonator.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a National Stage of International patent application PCT / EP2009 / 066655, filed on Dec. 8, 2009, which claims priority to foreign French patent application No. FR 08 07002, filed on Dec. 12, 2008, the disclosures of each of which are incorporated by reference in their entireties.FIELD OF THE INVENTION[0002]The invention relates to pyrotechnic charges, notably those used in the oriented multiple burst military domain.BACKGROUND OF THE INVENTION[0003]The military warheads, such as those of missiles, rockets, etc., comprise pyrotechnic charges intended to destroy or damage a target located nearby. The activation of the charge is controlled by electronic devices embedded in the military warhead detecting the presence and the position of the target to be destroyed.[0004]The military devices that include such pyrotechnic charges and their ignition devices are constantly changing to become more effective while offering a high l...
